Abstract: ABSTRACT OF THE DISCLOSURE       An apparatus for the continuous thermal treatment of a product within an atmosphere made up of steam (saturated or superheated) of pure water or of a mixture of air and water vapour is disclosed.  The product moves through an enclosed or confined space for its thermal treatment by the steam.  The space is provided with entry and exit air-locks for the convey-ance of the product into the space and for its removal.  There are also means for guiding the product through the air-locks and the space. Additional means is provided to encourage ther-mal treatment and hence the space is provided with convection, radiation or conduction means to bring heat to the product. A first condenser receives vapour or humid air which is preferably extracted from the enclosed space via the adjacent air-locks; it provides heat recovery of the purged vapour from the space.          A second condenser is placed within the enclosed space and communicates with the high pressure discharge port of a com pressor.  The compressor has its low entry port communicating to an evaporator of the first condenser. It is the second condenser which supplys to the enclosed space heat that is derived from high pressure steam, at the output of the compressor.

Abstract: COMPENSATING TIME-BASE ERRORS IN A REPRODUCED VIDEO SIGNAL .                    ABSTRACT OF THE DISCLOSURE     Apparatus for use with a video signal playback system of the type which reproduces a previously recorded composite color video signal wherein time-base errors appear in the lumi-nance component of that video signal.  The apparatus modifies the chrominance component of the composite video signal 80 as to have time-base errors in correspondence with the errors in the luminance component.  The luminance and chrominance components are separated from the composite color video signal; and a local subcarrier reference signal is generated to have the time-base errors which are present in the luminance component.  This local subcarrier reference signal is essentially substituted for the subcarrier of the reproduced chrominance component, thereby imparting such time-base errors into the chrominance component. At least the luminance  component is delayed by an amount equal to a horizontal line interval so as to equalize the time-base errors which have been imparted into the chrominance component with those time-base errors which are contained in the reproduced luminance component.  The delayed luminance component and the substituted-subcarrier chrominance component are combined so as to reform the composite color video signal.     -i-

Abstract: ABSTRACT OF THE DISCLOSURE        A single hydraulic supply line feeds fluid under pressure to a hydraulic percussive machine with a percussion motor and a rotation motor.  The feed passes through two valves of the constant volume priority flow dividing type.  The first valve gives priority to the percussion motor to the extent of establishing idling speed.  The second valve in the bypass of the first valve gives priority to the rotation motor while its bypass reaches the percussion motor. Working speed of the percussion motor can only be obtained after the rotation motor is up to speed and control of the feed above the priorities controls the percussion motor speed only.

Abstract: ABSTRACT            Graphical data on a document is raster scanned and the resulting bit pattern is processed to provide a processes-bit-pattern which represents single-pel-wide lines indicative of the shapes of objects scanned on the document.  These single-pel-wide lines may represent the outlines of objects on the centre lines.  The processed bit pattern is then passed to a line follower in which bits representing contiguous pels are detected and tested for linearity.  When contiguous pels fall the linearity test, a new vector is started and the vector being tracked is terminated.  Hardware for performing these operations is described.  The resulting vector list is stored until needed for display etc.  Optionally a display station can be used to correct faulty vectors or to encode alphanumeric data in a more convenient format than vector coding.

Abstract: ABSTRACT OF THE DISCLOSURE      A light-emitting semiconductor device of the type having a substrate, a first layer of a semiconductor on the substrate and a second layer of a different con-ductivity on the first layer.  The second layer is selectively voided so as to give a recess and leave the first layer uncovered in a region serving as the bottom of the recess.  An ohmic electrode layer is selectively formed on the second layer so as to extend into the recess and contact with the uncovered region of the first layer, and another ohmic electrode layer is selectively formed on the second layer so as to be separated from the former electrode layer.  A solder bump is built up on the first electrode layer to fill up the recess and another solder bump on the second electrode layer so as to be separated from the former solder bump.  Selective voiding of the second layer is accomplished by initially covering the entire area of the first layer with the second layer and then selec-tively slotting the second layer to a depth greater than the thickness of the second layer.
